This test is typically performed to diagnose or evaluate conditions that affect the blood vessels, such as aneurysms, blockages, or narrowing of the arteries, blood clots, or arteriovenous malformations.
When this test is required
This test may be requested by a doctor or specialist when a patient presents with symptoms that suggest problems with their blood vessels. It may also be used to monitor the progression of a disease or the effectiveness of a treatment.
What the Test Detects
During the CT angiogram run-off, a contrast dye is injected into a vein in the patient’s arm. The dye travels through the bloodstream and highlights the blood vessels on the X-ray images. The images are then used to create a detailed 3D image of the blood vessels.
Preparation for the Test
The preparation for this test may vary depending on the specific medical facility and the patient’s medical history. Generally, patients are asked to fast for several hours before the test and to avoid certain medications. It is important to follow the specific instructions provided by the medical facility.
Sample Requirements
No sample is required for this test.
Additional Notes
The test involves exposure to radiation, and the contrast dye may cause allergic reactions in some patients. It is important to inform the medical staff of any allergies, medical conditions, or medications before undergoing this test.
